As already mentioned, this wasn't a shocker, but it just has so many holes. I think the biggest one is Obito's motivation.
From Kakashi Gaiden, you couldn't sense a shred of evil intention from Obito. The only thing I could possibly think of is if Kakashi failed to save Rin in another mission or something (which could be the empty promise Obito referred to), but even that seems kind of petty...
Pretty much this.
EDIT:
Who needs to wait for the final antagonist? Haku, Gaara, Neji, Kimimaro, Sasuke, Nagato, Yahiko.
EDIT 2:
While I agree that a character can just be evil, I feel like there should be a reason in some situations like this (Obito makes a complete 180 in such a short time). Just thought I should say that since I mentioned I had no problem with Tobi being Tobi, but felt an explanation was in order when it was revealed to be Obito.

Kishi has some explaining to do, and he better not bs this around
Pretty much this.
EDIT:
WHOA THE FINAL ANTAGONIST BEING AN ANTITHESIS TO THE PROTAGONIST SO SHOCKING IN SERIALIZED STORY-TELLING I MEAN IT'S NOT LIKE THAT TROPE ISN'T OVERUSED AT ALL REALLY
